Re-Sizing .311 Projectiles for .300 Whisper...

[Hoser]

You need to get a bullet resizing die to size them down. I have a CH4D die. Be warned, it actually takes a lot of oomph to push a jacketed .311 bullet through a .3085 die. I did a couple thousand ZMax bullets a while back and it was painfully boring. I would just do a little each day, they eventually got done.

Thanks, Hoser.

I have a Lee 308 resizing die and might decide to do this...once I finish up all of the other reloading projects on my bench.

I also found a similar post on the 300BLK forum:

How does the Ruger Mini 30, with a .308 barrel handle .311 ammo without problems?

I just ran a hundred85 gr. .312 XTPs through a Lee .308 sizing die to try in the Whisper. They sized down just fine - seem consistent. I'll try loading them over some Trailboss and see how they do. Hopefully I'll get to try them out in a day or two.

Different bullets will react differently to this. I once sized down some .323" 8mm bullets to load in a .318"-barrelled Mauser. The core became loose from the jacket. Turns out the jacket will spring back a bit while the lead core stays smaller, creating looseness. The solution, IF this happens to you (doesn't always), is to size a couple thousandths smaller than your desired final diameter, and then run the bullet through a bump-die to re-expand the whole thing to final diameter. Then, the core and jacket stay firmly swaged together.

I bought 1000 .311sp 123 grain bullets years ago to load in my sks, then the price dropped to about $100 per 1000 delivered. It was cheeper to shoot the mil stuff than reload, so about 5 years ago with my new 300 fireball barrel I loaded up a bunch of the .311sp and fired them through the .308 barrel to break in my new action and get thing loosened up. No problems, just went to sub loads with a can and heavy bullets so haven't shot any for a while now.

I have a complete derail here, but please pardon my ignorance, what exactly do I need to do to load of cast boolets for my 300wtf? I know I need some sort of expander, but going through Midwayusa, I am not sure which one I should be looking for.
